CMS Analog series foot mounted solenoid driven metering pump fits small and medium dosing applications. They are constituted of the following main assemblies
This solenoid driven pump works in an intermittent mode. A magnetic field is created each time a pulse reaches the magnet. The magnetic field pushes the piston. A diaphragm (fixed on the piston head) compresses the liquid into the pump head. The liquid gets out through the delivery valves while the suction valves close. When the pulse ends, a spring takes back the piston and the diaphragm. The vacuum created by the diaphragm movement takes the liquid inside the pump head from the suction valve, while the delivery valve is closed. The pump capacity is proportional to the number of strokes and to the pump head internal volume.
Box: The CMS Digital series dosing pumps are assembled in IP65 (PP and glass fiber) plastic enclosures. Installation is wall mounted by means of two screws at a distance of 152 mm.
Electronic Circuit: The electronic circuit is made of proved quality components. It provides the necessary electrical pulses to the magnet.
Electro-Magnet: The electro-magnet with class H (180°C) copper winding, driven by the electronic circuit, gives the necessary force to the piston and the diaphragm. Piston stroke length varies from 0.7 to 1.7mm, according to the pump type (pressure/output).
Diaphragm: PTFE diaphragms used in the CMS Digital series pumps assure good chemical compatibility and mechanical resistance.
Pump Head: CMS Digital series Pump Head diameters are ø22, ø32, ø44, ø58, ø64. The pump head works as a dosing chamber, the suction valve, delivery and manual outgassing valves are inside it. The purpose of the manual outgassing valve is to help the priming of the pump during installation.Pump head is made in PP and upon request PVDF."
